' To all whom it may camera:

Be it known that I, Gnonon Manmnnn, a citizen of the'United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, havev invented certain new and useful Improvements in Box-Car- Loading Machines, of which the following is a specification reference being bad to the accompanying drawing, forming apart thereof.

This invention relates to box car loading machines and the objects of the invention are to i prove box car loadin machines in the manner to behereinafter described and claimed. 1

Referring to the drawings which accomany this'specificatio'n and form a part hereof, which drawings illustrate an embodiment of this invention, and on which drawings the same reference characters are used to designate the same parts wherever they may appear in each of the several views, Figure 1 is a plan viewof part of a box car loading machme', a part being shown in section; Fig. 2 is an elevation of parts of the machine looking in the direction of the arrow a on Fig. 1, parts being broken awa Fig. 3 is an elevation of parts of the mac ine looking in the direction of the arrow 6 on Fig. 1, parts being broken awa and Fig. 4 is a sectional view of parts of t e machine.

Referring to the drawings, the reference numeral 1 designates a supporting member to which are secured bearings 2 and 3; The bearings 2 and 3 hold a shaft 4 in properposition and thisshaft supports the arms 5 l and 6. The arm 6 sup orts a yoke 7 which carries the conveyer not shown). Each of the bearings 2 and 3 is provided with an aperture therethrough and the upper part of the bearing 2 is provided with the con-- cave seat 8 'of a ball and socketjoint in which the ball 9 .of the-ball and socket jointrests. The-ball 9 is preferably formed; asan integral part of the-housing 10 within which the u per end. of the shaft 4 is slidabl receive the shaft'fitting'snugly the re uced Y bpre 11 in the housing; The lower end of the shaft 4 is prefera nated by the reference numera1'12 for a suitable distance and adjusting bolts 14, 15 16 and .17, provided. with lock nuts, screwed through screwthreaded apertures in bearing 3 are adapted to bear against the squared lysquared as, desigsides of the sh: 1ft 4 to hold the shaft in vertical alinemenl. The supporting member 1 for the machine may be a special post or a part of a bridg e conve er, or any convenient structure, and the adjusting bolts 14', 15, 16 and 17- witl. the ball and socket joint between the bearing 2 and the housing 10 provide a form 01 universal adjustment so that the shaft 4 car he set vertical in the first instance or made vertical if the supporting member 1 should change its position.

, The upper end of the shaft 4 is provided with the count erbored bore 18 for the screwthreaded .shaf; 19 which engages with the bronze'nut 20 rigidly and securely fastened to theshaft 4 in any suitable or preferred manner... The shaft 4 and the parts of the machine carriul thereby are supported from the top of th housing 10 by means of the screwthreaded shaft 19, bevel gear 21 keyed nut 23. To leduce friction, ball hearings, or other suitable antifriction devices, are interposed betw aen the top of the housing 10 and the bevel gear 21. A stud 24 is secured to the housing 10 and carries a bevel gear 25 which meshes with bevel gear 21 and which is provided on its hub with ratchet teeth 26 by me ans of which and pawl mechanism carried by the actuating handle 27 the bevel gear 25 canbe rotated in either direction to r aise or lower shaft 4 and the parts of the machine carried thereby. The adjusting screws which bear agamst the squared, lOWtI; end ,of shaft 4 prevent its being rotated by the screwthreaded shaft 19.

A collar 2:; is fastened to shaft 4 by a pin 29, or in anyother suitable manner, to support arm 5. Ball bearings 30, or other suitable antif riction devices, are interposed between the follar 28 and the lug 31 proor otherwise secured thereto, washer 22 and jecting from arm 5 and roller bearings 32 form a hinge joint therewith.

Arm 6 ishinged to arm 5 by the intles $5 and 36 andis supported upon bal bearlugs 37, or )ther suitable antifriction devices, and provided with antifriction devices 38 and as engaging pintles 35 and 36, to

avoid frictioi 1, the same as arm 5.

The yoke 7 is fastened to pivot 40 by a pm 41 and ball hearings, or other suitable both above antifriction devices, 42'and 43 avoid fricand below arm 6 are provided to tion.

The arms 5 and 6 are preferably made as hollow castings and segments 44 and 45 pass through core holes 46 and 47 in the arms. These segments are provided with teeth and bolts 48 and 49, held in guides 50 and 51 secured to the arms 5 and 6, and pressed toward the segments by springs 52 and 53, are adapted to enter the spaces between the teeth and so lock the arms in any selected positions of angular adjustment about their respective hinges. Segment 45. is securely fastened to arm 5 and segment 44 is securely fastened to a bar 54 which may be made integral with the collar 28 and one arm of which terminates in a ball member 55 engaging with a guide 56 secured to. the supporting member 1. The objects of this construction are to relieve the adjusting bolts at the lower 'end of shaft 4 from the strains to which they would be subjected if segment 44 were merely secured to shaft 4. The guide 56 is long enough vertically to provide for the extreme movements of shaft 4 when it is raised or lowered. The ball member 55 on the bar 54 permits a close fit of the ball member within the guide while permoved by the admitting the shaft 4 to be j usting screws or bolts 15 and 17, such movements causing the ball member to be rocked within the guide. Theclose fit of the ball member within the guide is not an abso lutely close fit but is closeenough to preverlilt any undesirable movements; or backlas v I In order that the bolts 48 and 49 may be simultaneousl withdrawn from engagement with the teetli of the segments 44 and 45 so that the arms 5 and 6 may be turned or swung as desired they are connected to common illustrate hand levers 58 and 59 located on opposite sides of arm 6 and .rigidly connectedto the shaft 60. A foot lever 61 is fastened to the bell cranks 62 and 63, which end of arm 6, and these bell cranks areconnected by means of links 64 and 65 with the disks of the hand levers 58 and 59 which serve. as hell cranks, or cranks, for the'purpose of transmitting motion. Both bolts 48 and 49 are connected with the disk of hand lever 58 by any suit able or preferred connecting devices. The preferred form of these connecting devices, as illustrated by the drawings, comprises levers 66 and 67 which are pivoted to the arms 5 and 6 and to the bolts 48 and 49. Flexible connections 68 and 69 are used to connect levers 66 and 67 with the disk of the hand lever 58 so that the bolts 48 and 49 can be moved independently by their springs. The connection 68 would vary in length as arm 6 is swung with respect to are pivoted to the operating mechanism. The drawings arm 5 unless some special means were interposed to maintain this connection of substantially the same len h. These means are the bell cranks 70 and 1 which are 4 respectively, to the arms 5 and 6. 'These bell cranks have a form of hinge connection in the axis of the pintles 35, and. 36. 'In the specific construction illustrated by the drawings, one arm of hell crank 70 is provided with a yoke or recess located in 'xis of the pintles 35 and 36 and one arm of the bell crank 71 is ball shaped and is bent into the axis of the pintles 35 and 36 so as to engage within the yoke or recess of bell cran 70.

The operation of the machine will be readily understood from the foregoing description of the construction. The shaft 4 can be adjusted to a vertical position, a matter of importance because the arms 5 and -6 and the mechanism carried thereby are heavy and, if the shaft 4 were not vertical or substantially so, it would-require considerable labor to swing the arms. The arms can be locked in position or unlocked and the three levers permit this to be done from a any one of three positions which may be occupied by the operator. The conveyer (not shown) and the arms 5 and 6 can be raised or lowered to suit the conditions 'of loading or the differences 'in heights of cars.
